PAUL, MINNESOTA, ASSIGNOR TO NORTHWESTERN METALWARE GOMPAN Y, OF MINNEAPOLIS, MINNESOTA, A CORPORATION 0F DELA- WARE LIQUID FUEL BURNER STOVE Application filed August 9, 1930. Serial No. 474,096.

This invention relates to liquid fuel burner stoves and it relates particularly to stoves of the type used for brooder stoves. In such brooder stoves, there is a casing which surrounds the burner head and this casing at its upper end is usually provided with an opening directly above the burner head closed by a cover plate. There is generally a spreader plate disposed in spaced relation above the burner head and this spreader plate prevents free access to the burner head when the cover plate is removed to permit of removal of carbon and dirt from the burner head. Also it is very difficult to obtain access to the burner head to light the liquid fuel therein, `unless an opening is provided inthe casing at one side of the same. Also it is often desired to adjust the height of the spreader plate relative to the burner head and to an apertured partition that is usually provided above the burner head and below the spreader plate.

It is the object of this invention to provide in a liquid fuel burner stove of the class described a construction whereby the spreader plate can be removed with the cover plate to permit of ready access to the burner head, a construction whereby the liquid fuel can be readily ignited without use of side doors in the casing of the stove and a construction wherein the spreader plate can be adjusted to and from the burner head, while the cover plate is applied to the casing.

To these ends the invention consists in the novel parts and novel combinations of parts, hereinafter dened in the claims and de` scribed in the following specification, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the .various views, and, in which,

Fig. 1 is a vertical section taken through a liquid fuel burner stove-of thertype used for a brooder stove embodying the present invention, certain of the parts being shown in a lowered positionin full lines and in a raised position in dotted lines; and

Fig. 2 is a view illustrating the lower portion of therod shown in Fig. 1 with waste or similar starting material applied thereto.

Referring to the drawings, certain portions of a liquid fuel brooder stove are illustrated, which include the base 3, cylindrical casing 4, burner head 5, partition plate 6, liquid fuel supply conduit 7, overiiow conduit 8 and chimney 9. The casing 4 adjacent its lower end is provided with a series of air draft openings 10 and the burner head 5 may be formed integral with orsecured to a horizontal divided plate 11 having aseries of openings 13 therethrough to permit the circulation of air to the burner head. The burner head 5 has a well 12 at its central portion to which the liquid fuel is fed by means of the supply conduit 7 and one or more overflow grooves 14 concentric with the well 12 are provided in the burner head, the overilowvconduit 8 being disposed in the outermost groove 14. The partition plate 6 is disposed in spaced relation above the burner head 5 in a horizontal plane and a central opening 15 is provided in the partition plate above the well 12 of the burner head. The top of the casing 4 may be provided adjacent one side of the casing with a anged opening over which the smoke pipe 9 is placed. Asis usual in such a stove, the top of the casin 4 is provided with a central down set portion having quite alarge opening 16 therethrough,

the down set portion having an inwardly projecting flange upon which acircular cover plate 17 may rest.

In accordance with the present invention, a rod 18 is centrally mounted in the cover plate 17 to project downwardly therefrom through the opening 15 in partition 6 and into the well 12 of the burner head 5. The cover plate 17 will preferably be provided with a screw threaded apertured hub and the upper end of the rod 18 will preferably be screw threaded to fit within the screw threaded aperture of the hub of the cover plate for adjustment of the rod lupwardly and downwardly relative to the cover plate. A nger ring 19 is secured to the upper end of the rod 18 above the cover plate. A circular deiector plate 2O of smaller diameter than the central opening 16 in the top of the casing is secured to the rod 18 as by means of a set screw 21 below the cover plate 17 and in spaced relation above the partition 6. The

lower end of the rod 18 will preferabl be pinched outwardly at its two sides to orm small wings 22 for the retention of waste A pir similar igniting material, as illustrated in lingue to the fact that the rod 18 is mounted in the cover plate 17 andthe deflector plate 20 is carried by the rod 18, it will be seen that the cover plate and the deflector plate can both be simultaneously raised with the rod 18lfrom the casing 4 to permit of free access through the opening 15 to the burner head 5 foa` cleaning carbon or other dirt therefrom. It will also be seen that the relative adjustment between the deflecting plate 20 and the partition plate 6'and burner head 5 can be varied while the burner is in operation and while the cover plate 17 is fitted over the opening 16 by merely turning the rod 18 relative to the cover plate 17. To ignite the burner when first starting the same, it is only necessary to raisethe rod 18 out of the casing 4 thereby removing both the cover plate 17 and thedeflector plate l2O, whereupon a small quantity of waste A or similar igniting material may be wound about the lower end of the rod 18, the wings 22 holding the waste in place. The rod and plates 17 and 20 can then be reinserted in place'to dip the Waste A in the well 12 which will preferably have been supplied with a small quantity of liquid fuel, and the waste will then be impregnated with .the fuel. The rod 18 can then again be removed from the casing and the waste ignited whereupon by again reinserting the rod 18 and the two plates 17 and 20 in place, the' fuel in the well .12 may be ignited bythe flaming waste or similar igniting material.

It will be seen that a very simple const-ruction is providedl` for eifectivel accomplishing the purposes intended. T e present device has been amply and successfully demonstrated in actual practice.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of the present invention, and it will further be understood that the present invention may be used in connection with brooder stoves or in connection with any other type of liquid fuel burner stoves.
